Now xt_tgchk_param par in ipt_init_target is a local varibale,
par.net is not initialized there. Later when xt_check_target
calls target's checkentry in which it may access par.net, it
would cause kernel panic.
Jaroslav found this panic when running:
# ip link add TestIface type dummy
# tc qd add dev TestIface ingress handle ffff:
# tc filter add dev TestIface parent ffff: u32 match u32 0 0 \
action xt -j CONNMARK --set-mark 4
This patch is to pass net param into ipt_init_target and set
par.net with it properly in there.
v1->v2:
As Wang Cong pointed, I missed ipt_net_id != xt_net_id, so fix
it by also passing net_id to __tcf_ipt_init.
v2->v3:
Missed the fixes tag, so add it.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
